(PHP 5 >= 5.3.0, PHP 7)
Represents a date interval.
A date interval stores either a fixed amount of time (in years, months, days, hours etc) or a relative time string in the format that DateTime's constructor supports.
More specifically, the information in an object of the DateInterval class is an instruction to get from one date/time to another date/time. This process is not always reversible.
A common way to create a DateInterval object is by calculating the difference between two date/time objects through DateTimeInterface::diff().
Number of years.
Number of months.
Number of days.
Number of hours.
Number of minutes.
Number of seconds.
Number of microseconds, as a fraction of a second.
Is 1
if the interval
represents a negative time period and
0
otherwise.
See DateInterval::format().
If the DateInterval object was created by
DateTime::diff(), then this is the total number of
days between the start and end dates. Otherwise,
days will be FALSE
.
Before PHP 5.4.20/5.5.4 instead of FALSE
you will receive -99999 upon
accessing the property.
